TMUI unresponsive after tab switching #6

Open kreynoldsf5 opened 4 years ago

kreynoldsf5 commented 4 years ago

Within the FAST App LX, tmui will become unresponsive by switching tabs, quickly, from templates to some other tab and then back to templates.

The following is displayed: ...Loading Template List...

immediately prior to the unable to contact the BIG-IP device dialogue. Refreshing the browser allows access to tmui.

When the UI is loaded, it makes calls to iControl REST to fetch information from the box. The deploy log specifically makes calls to AS3 that make subsequent calls to gather information about jobs run by AS3. By switching tabs rapidly, it is probably sending and then abandoning these calls and they are stacking up and overwhelming iControl REST/LX.

Recommendation for now is to wait for pages to fully load before clicking into any other tabs. Do not rapidly attempt to delete applications on the applications tab.

We can re-organize the GUI loading so this type of rapid clicking is not possible. We are tracking this in our internal Jira as MYSTIQUE-84.

Followup question, how rapidly and how many times do you need to switch tabs before the UI becomes unresponsive?
